Accelerating For Passing
Push the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
FOUR WHEEL DRIVE — JEEP ACTIVE DRIVE
(4WD) AND JEEP ACTIVE DRIVE LOW (4WD
LOW)
Your vehicle may be equipped with a Power Transfer
Unit (PTU). This system is automatic with no driver
inputs or additional driving skills required. Under nor-
mal driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a preemptive effort to improve vehicle
launch and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.
